摘　　要：介绍了从溶液中提取铷和铯的工艺研究现状以及用于提取铷、铯的新材料。重点概述了沸石、杂多酸、亚铁氰化物及硅钛化合物在铷、铯提取方面的应用。溶剂萃取分离提取铷、铯最具有工业化前景,常用的萃取剂是t-BAMBP。杯芳烃冠醚将有可能用在高放废液处理方面,降低其合成成本是今后的主要研究方向。Status of extraction technique in rubidium and cesium recovery and new material for extrac- tion of rubidium and cesium from solution are introduced. The application of inorganic ion exchangers included zeolite, heteropoly acid, ferrocyanide, and silicotitanate at extraction of rubidium and cesium were overviewed. Extraction is the most prospect industrial separation method and t-BAMBP is com- monly used in recovering rubidium. Calixcrown ethers are promising materials for removal of cesium from high level radioactive effluent, but to reduce the synthesis cost of calixcrown ethers will be the main research aspect in the future.
